Given numbers are 147, 977, 900, 421

The list of prime factors of all numbers are

Prime factors of 147 are 3 x 7 x 7

Prime factors of 977 are 977

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

Prime factors of 421 are 421

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 147, 977, 900, 421

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(147, 977) = 143619

GCD(147, 977) = ( 147 x 977 ) / 143619

= 147 / 977

= 147

Step2:

LCM(1, 900) = 900

GCD(1, 900) = ( 1 x 900 ) / 900

= 1 / 900

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 147, 977, 900, 421 is 1
